Regularly Check The Wear of Fixing Bolts of Diesel Generator Set

Aug. 24, 2023

How to regularly check the wear of the keyways and fixing bolts related to diesel generator sets, using standard high-pressure oil pipes. During the fuel supply process of the fuel injection pump, due to the compressibility of diesel and the elasticity of the high-pressure fuel pipe, high-pressure diesel will form pressure fluctuations inside the pipe. The transmission of pressure waves inside the pipe requires a certain amount of time. To ensure consistent fuel supply interval angle, uniform fuel supply, and stable operation of the diesel generator set, the length and diameter of the high-pressure fuel pipe are selected through calculation.

Therefore, when the high-pressure oil pipe of a certain cylinder is damaged, a standard length and pipe diameter oil pipe should be replaced. In practical use, due to the lack of standard oil pipes and the use of other oil pipes instead, regardless of whether the length and diameter of the oil pipes are the same, there is a significant difference in the length and diameter of the oil pipes. Although it can be used for emergency purposes, it will cause changes in the fuel supply advance angle and quantity of the cylinder, resulting in unstable operation of the diesel generator set. Therefore, it is necessary to use standard high-pressure oil pipes in use.


And it is necessary to regularly check the wear of the relevant keyways and fixing bolts of the diesel generator set. The relevant keyways and bolts mainly refer to the camshaft keyways, coupling flange keyways (oil pumps that transmit power through couplings), half round keys, and coupling fixing bolts. The camshaft keyway, flange keyway, and semicircular key of the fuel injection pump may wear out due to long-term use, causing the keyway to become wider, the semicircular key to not be firmly installed, and the fuel supply advance angle to change; The heavy key falls off, causing power transmission failure. Therefore, it is necessary to regularly inspect, repair or replace worn components in a timely manner.
